I saw someone with a Nexus 5 yesterday. He carries a huge external battery pack (at least twice the size of the phone) and re-charges 2-3 times daily! He would love 16 hours battery life.

I agree with those who place battery life over thinness and weight. Once a device is thin and light enough (e.g. iPhone 4), I'd rather have one that lets me do more in a day.

I'd rather wait and see what the real product is like before I worry about battery life based on rumoured specs. If Apple can really manage to improve battery life without significantly increase the size of the battery it's better because I dont have to charge it for too long.
 
Whiners should post screencaps so we could determine how bad is iPhones battery life...

Most of them never touched an iPhone. All they know is what samsung tells them in their commercials.

My screenshot is much better than your words.

Apple doesn't need to put an humongous battery on the iPhone, just because android manufacturers need to do that because android is so inefficient with battery life.

Your screenshot shows you had it on, but not what you used it for, what brightness levels, what websites you visit (I don't expect you to disclose this, but it should be known that some websites are a lot worse on battery than others). Also, having constant wifi access is a lot easier on your battery than 4G in an area with spotty reception (we can't tell if you used wifi the whole time based on your screenshot).

That being said, for myself getting an iPad was probably the easiest way to increase my 4S's battery life. :D
 
that is not fact, that is just a screenshot of your setting, on which your phone reports your battery life, a report that fluctuate percentage based on your current usage. if i drain my battery down to 40 percent, and thn killed ALL THE APPS, i too would get 7 hours of battery with 40 percent charge.

so unless you got some magic gold battery, your reporting of you using your phone with all these apps and settings on on a "medium usage" and still getting 2 days of charge is plain BS.

battery is a big issue with iphones, the more a consumer like you deny it the less likely apple would do anything to improve it. so do us a favor and stop denying the obvious.

Thank you! I was about to write that, but then couldn't be bothered to even try to prove the obvious
 
Apparently this needs to be explained to everyone...

You're going to see an improvement, in some ways potentially huge, in battery life no matter what with the iPhone 6.

Let's assume you're coming from an iPhone 5.

  • You're going from a 32nm processor to a 20nm processor.
  • You're going from LDDR2 to potentially LDDR4, which uses less voltage.
  • You're going from a second generation LTE chip, to a mature, more energy efficient LTE chip.
  • That LTE chip gets better signal due to added frequencies and therefore drains less battery.
  • You're almost assuredly going from a 1x1 802.11n antenna array to a 2x2 802.11ac WiFi antenna array, meaning less power needs to be output to send and receive data, and the wireless chipset can go to an idle state faster.
  • The battery capacity is going from 1440mAh to 1810mAh, a 26% improvement in capacity.

Battery life is going to be much better.
 
If Sony, HTC and Samsung can use bigger batteries (and removable batteries for the Samsung phones), I don't know why Apple can't?

The thickest phone in the list is the Note 3, and it's not even 1mm thicker than the 5s.

Wow, is that really hard to see that those phones have much more surface area?

And really hard to see that smasung phones are made of plastic, and have clip-on covers?
 
It's a fact.

Like the benchmarks on anandtech, gsmarena, and other credible sources.

You don't even have an iPhone 5S to argue whatever with actual users.

Costumers complain about battery, because they were forced to believe that by aggressive marketing strategies from samsung and others, not only in ads, but also in sales tactics.

Because in fact, any android's battery life is crap compared to ios, most people on android are in satisfied with battery life, going leaps and bounds, like installing custom ROMs and custom kernels.

On the other hand, most people on iOS, tend to keep their phones more time, and in turn wear more the battery, while on android fans, most of them rarely really use their phones as a smartphone, they have that paranoia of turning off everything and change their smartphones every 6 months.

first off, i have a iphone 5s, so keep moving on that one buddy. would you like me to post pointless pictures of all my iphones as well?

2nd. where do you even see me using a android phone as a benchmark or any sort of bench setting. i'm using REALITY as benchmark, the fact that i have to go power outlet hunting at 5pm because my phone can't keep up with my schedule should warrant enough of a reason to have this conversation.

and 3rd, IT IS NOT A FACT, how can you even compare your messy screenshot of your setting, which is easy as hell to manipulate, to anatech and other review website's benchmarks' graphs, polls. and numerous data output charts and manage it to relate to your screenshot, and calling it a fact.

I'm looking forward to my move from my 5 to the 6, though battery life isn't an issue for me.
 
How many times can you charge your precious galaxy note 3 from a power bank?

What if you want to live 1 week away from power grids?

You're right, my Note 3 is precious to me, best phone I've ever had :)

And to be honest with you, if I have to live 1 week away from power grids, technology is the last thing I care about :)

But what I know something for sure: I unplug my phone at 5:40 in the morning, and after a day of heavy usage (games, phone calls, ~5hours screen time, Facebook, Twitter, SMS), I plug the phone at 10PM. Battery life remaining: ~30-35%. It has been the same for the last 3 weeks

With light usage, I can go 2 days without recharching it. IMO, that's what the iPhone 6 must be able to achieve. That what current flagship Android phones can achieve.

Don't you think that if technology allowed it would have been invented already.

same for android phones. And you know what's worse? Since most Android phones' battery size is so much larger it takes forever to charge the battery.

Nonsense FUD. Have you ever charged a battery using USB 3.0?

----------

I wonder the same, how is it even possible to get 2 days with heavy usage out of a single charge??? I wonder what your definition of heavy is.

Moreso, what is being used with all of those features being turned off?

1st, then what's good out there? Tell me...

2nd, phones allways need to charge. Even if they last for a week. Sorry if you don't understand that.

3rd, at least I have a screenshot.

Also, some sites out there agree with me...

http://www.anandtech.com/show/7335/the-iphone-5s-review/9

It may not be the best, but power/battery and battery/weight, it is.

So, if you want to complain, complain about other phones that all have a sucky battery life.

And tahts a fact, the only "proof" of the iPhone have poorer battery life is from android fanboys that don't have an iPhone to begin with, and will never have,nbecause its too hard for them to understand that just a bigger battery won't make a phone last longer.

I used it as normally, as I allways do, and doesn't matter what I did, 7 hours is a lot. I always have all radios on (4g, wifi and bt), my phone never let me down.

Good post.

Also, the 6 should be using an IGZO a screen, which also helps.

now my words are as legitimate as yours
 
Can someone with knowledge in the area please provide their opinion on how much of a boost (if any) this will provide taking into account a larger screen?

Does a 1810 mAh sound about right to keep the current battery life with a larger screen? Or is it impossible to tell?

Looking only at the numbers, it's a 16% bigger battery (1560 mAh -> 1810 mAh) with a 18% bigger screen (4" -> 4.7"). Considering that the screen has an energy impact about 100x greater than the CPU, any energy savings in the CPU will hardly improve battery life.

So these napkin calculations say that the battery life will be 116/118 ~ 99% of what it was before. So we may see the slightest drop in battery life and Apple will ignore it and advertise it as having the exact same battery life as before.

Comparing it to my iPhone 4S... I'm getting a 27% bigger battery (1430 mAh -> 1810 mAh) with a 34% bigger screen (3.5" -> 4.7"). So I'll have 127/134 ~ 95% of what it was before. And I hate the battery life on my iPhone 4S. I really hope that these napkin calculations suck and that I have some majorly flawed assumptions here.

It's funny because you are the third person to make this same calculation. The screen would be ~38% bigger by surface area (the only superficial measurement that would matter in this case).

Still doesn't help us very much to calculate battery life, unfortunately.
 
Guys, the most battery drain is caused by the display. So even if A8 uses half of the energy of A7 you won't get a huge difference.

I don't understand why nobody invented a phone with huge 4k battery. I would probably prefer it over ultra slim design.

The Motorola droid maxx has a 3.5k battery. I don't understand why other phone manufactures don't put larger batteries in there phones. I have the maxx and think it is currently the best phone on the market. Also moto designed the phone to be efficient. They use a 5" 720p screen. I think 720p is perfect for phones.

I say Igzo technology, A8 chip optimized for power savings,and newer chips will give it nice battery life. The iPad Air has a smaller battery and gets decent battery life. Also it has a Igzo display.

If you're right, the whiners on these forums are going to have to find something else to complain about.

Which will take all of one day, if not less.
 
Goodbye iPhone. Hello Moto X2

Ha! The Moto X is the phone that made me decide to make the switch from iOS to Android, but let me tell you, it ain't so great, and as soon as I can get my hands on an iPhone 6, I'm going to drop my Moto X like a hot potato. It's like they say, the grass is always greener on the other side. Save yourself the trouble I went through and just stick with iOS!
 
1. Most of the rumors are just rumors.
2. Apple will release an updated iPhone with improved battery life.

Why does anyone care about the battery life of Android phones if you aren't in the market to buy one?
 
Since everyone is posting their battery experiences, I went from an iPhone 5 to a Samsung Galaxy S5 this year. The battery life is horrendous. The Ultra Power Saver mode makes it better, but it doesn't activate that mode automatically so if you happen to not be looking at your phone when it gives you the battery warning you're SOL.

Anyway, my iPhone was always on it's last leg at the end of the day, but I charge it every night. I basically have to leave my Galaxy plugged in all day. I plug it/unplug it so much the "waterproof plug cover" no longer stays fastened.

Enough with the trolling and BS, please.

The iPhone 5S with iOS7 - iOS7.1 easily has the worst battery life of any iPhone 4 - 4S we've used on Verizon with iOS 5/6.

A little dose of reality, probably won't help with your tin foil hat, denial, delusions, ... but here it goes anyways:




2.5 hrs = battery life half gone!

No gaming. Partial brightness. Most smart features turned off. 2-3 bars of VZW LTE.

If I actually use my 5S as a smartphone, I have to charge it at lunch, or it 'll be depleted by night.

If I drive anywhere am, lunch, pm ... I'm always charging my phone in the car.

And there are hundreds if not thousands of users just like me who get mediocre battery life, far from the 10 hrs of actual use Apple promises.

My 5S easily drops 15-20% per hour. Sometimes more. Avg is probably 15% = 6hrs

Momentarily thought that the screen diagonal length would be proportional to the screen area. Not sure how I made that mistake. You're right, it's 38% bigger from the 5S to the smaller rumored size of the 6, and 80% larger than the 4S (sortof. I cut corners and assumed the ratios were the same, but of course they're not. Should be something in that ballpark, though.)
